Current bridge design codes do not clearly specify the girder distribution factors for continuous bridges. The objective of the paper is to validate the use of code-specified girder distribution factors for the continuous steel girder bridges, and to provide a basis for recommended girder distribution factors (GDF) for interior girders, suitable for evaluation of existing continuous steel girder bridges. This paper presents the procedure and results of 3-dimensional finite element analysis that were performed on five of continuous steel girder bridges to verify girder distribution factors. The analysis results showed that the live load moment distribution at the negative moment region is very similar to those at the positive moment region in continuous steel girder bridges. It was also found that the GDF's based on the strain values are similar to those based on the deflection. GDF's based on the deflection show marginally better distribution. The analysis results confirmed that the code specified GDF's for continuous steel girder birdges are very conservative.

Purpose: This study aimed to investigate the factors affecting the subjective health status (SHS) of low-income older adults living alone. Methods: This is a cross-sectional correlational study using secondary data analysis. Sociodemographic and health-related characteristics were included in this analysis. The health-related characteristics were categorized into three domains: physical, characterized by the number of chronic diseases and fall-related factors, timed up and go, and grip strength; psychological, in terms of depression and loneliness; and social, in terms of social support. Data were analyzed using descriptive analysis, t-test, ANOVA, Pearson's correlation coefficient, and multiple linear regression analysis. Results: The mean SHS score was 2.46 out of five. Several factors influenced the SHS of low-income older adults living alone, including sex, age, level of education, monthly income, and the three domains. Four significant predictive factors of SHS in low-income older adults living alone were identified (42.5%): the number of chronic diseases, fear of falling, depression, and social support. Conclusion: SHS is a critical factor for older adults living alone on a low-income. Hence, evaluating SHS and developing interventions to improve it periodically is necessay. Such interventions should consider chronic disease management, screening and mediation for depression and fear of falling, and strengthening their social support systems.

This study was to identify the dimensions of consumers' attitudes toward imported casual brands. Another objectives were to examine consumers' attitude according to the preference group, and to ascertain the imported casual brand images. The 55 Likert type questions were selected through the results of self-questionnaire analyses. 520 females aged between 20 to 29 in Pusan responded to the second questionnaire of consumers' attitudes and brand images toward imported casual brands. The results were as follows: 1. For final factor analysis, 56 selected from 85 questions were subjected to the principal component analyses with orthogonal rotation after extraction of 5 major factors. 2. Five dimensions are brand's uniqueness and good quality, high prestige, incongruity with native emotion and ethnocentrism, conspicuous consumption, and reasonable purchasing advantages. These factors explained 45.0% of total variance. 3. Five dimensions were different according to the degree of preference. For preference group, they purchased the imported casual brands by uniqueness, good quality and reasonable purchasing advantages. For non-preference group, they disliked the imported brands by incongruity with native emotion, ethnocentrism, and conspicuous consumption. 4. Preference group had 5.47, whereas non-preference group had 1.76 pieces of imported casual brands for this 2 years. This result suggests that to develop the domestic brands with international uniqueness, good quality, and high prestige, and to improve according to preference group are necessary.

In this study, the effect of Internet clothing soho mall attributes on attitude toward site and revisit intention was investigated. A total of 292 female college students participated in the experiment to explore a clothing soho mall out of 20 highly-ranked soho malls for shopping and to complete a questionnaire. In exploratory factor analysis results, five factors were generated out of 18 question items indicating clothing soho mall attributes. Among those five factors, 'product assortment and presentation' was the most important factor affecting attitude toward site and revisit intention toward a clothing soho mall. In addition, 'site construct' was another factor affecting attitude toward a clothing soho mall site specifically in the group who shops clothing more often on the Internet shops than off-line shops. Based on study results, implications and insights were discussed.

Purpose: This study was aimed to analyze the contents and trend of published research in oncology nursing during the past five years in Korea and to suggest the direction for future research. Methods: Using the key words "cancer", "cancer patients", and "tumor", 391 nursing research published from 2003 to 2008 were selected for the analysis. Results: 1) Three hundred fifty-five (90.8%) of the studies used quantitative research approach, whereas most studies were descriptive in nature. 2) The main subjects of the study were cancer patients with mixed diagnosis (36.4%) and breast cancer patients (20.0%). 3) Complementary alternative therapy (28.9%), educational program (25.6%), and psycho-social and spiritual program (16.7%) were the most frequently used nursing interventions. Most frequently measured outcome variables were psycho, socio, and spiritual factors (38.8%), symptoms (28.2%) and physiological factors (14.6%). 4) Most frequently used key words were identified as quality of life, fatigue, coping, pain, anxiety, anorexia, and depression. Conclusion: The number of published research in oncology nursing in Korea has been increased. It is suggested to conduct international studies to develop, compare, and replicate nursing interventions for patients with cancer in future. Increasing funding, establishing research infrastructure, and removing methodological challenges are warranted for better research environment.

The purpose of this study was to develop landslide susceptibility analysis techniques using artificial neural networks and then to apply these to the selected study area of Janghung in Korea. We aimed to verify the effect of data selection on training sites. Landslide locations were identified from interpretation of satellite images and field survey data, and a spatial database of the topography, soil, forest, and land use was constructed. Thirteen landslide-related factors were extracted from the spatial database. Using these factors, landslide susceptibility was analyzed using an artificial neural network. The weights of each factor were determined by the back-propagation training method. Five different training datasets were applied to analyze and verify the effect of training. Then, the landslide susceptibility indices were calculated using the trained back-propagation weights and susceptibility maps were constructed from Geographic Information System (GIS) data for the five cases. The results of the landslide susceptibility maps were verified and compared using landslide location data. GIS data were used to efficiently analyze the large volume of data, and the artificial neural network proved to be an effective tool to analyze landslide susceptibility.

The purpose of this study was to investigate the effects of eating habits and food preferences on the adoptive behavior of children with intellectual disabilities. Survey questionnaires were distributed to six special education schools located in the Daegu-Kyungbuk area, and data were collected from 552 families and teachers with intellectually disabled students. Identification of eating habits began with a factor analysis, and the results were a five-factor solution. Among the five patterns, factors 1 and 2 were significantly related with behavior problems of intellectually disabled children. Further, food preferences of the children were significantly related with adoptive behavior problems. The findings of this study clearly indicate that eating habits as well as food preferences are important factors in identifying adoptive behavior problems in intellectually disabled children. Based on the findings of this study, similarities and differences in eating habits are discussed, and implications for children are provided.

I present an analysis of the long-term evolution of the fluxes of six active galactic nuclei (AGN) - 0923+392, 3C 111, 3C 273, 3C 345, 3C 454.3, and 3C 84 - in the frequency range 80 - 267 GHz using archival calibration data of the IRAM Plateau de Bure Interferometer. Our dataset spans a long timeline of ~14 years with 974 - 3027 flux measurements per source. We find strong (factors ~2-8) flux variability on timescales of years for all sources. The flux density distributions of five out of six sources show clear signatures of bi- or even multimodality. Our sources show mostly steep (alpha~0.5-1), variable spectral indices that indicate outflow dominated emission; the variability is most probably due to optical depth variations. The power spectra globally correspond to red-noise spectra with five sources being located between the cases of white and flicker noise and one source (3C 111) being closer to the case of random walk noise. For three sources the low-frequency ends of their power spectra appear to be upscaled in spectral power by factors ~2-3 with respect to the overall powerlaws. We conclude that the source emission cannot be described by uniform stochastic emission processes; instead, a distinction of "quiescent" and (maybe multiple) "flare" states of the source emission appears to be necessary.

The purpose of this study is to investigate Korean youth's motivations for parenthood and concepts of parental role and to examine closely the relationship with the sociodemographic variables(age, sex, religious orientation, growth region, father's occupational level, parental education degree). the subjects are 465 students of the three universities in National Capital region. The data are collected by questionnair methods and analyzed by t-test, F-test, factor analysis. The major findings are as follows: 1) The motivations for parenthood are classified into five factors. These are acquisition of social status factor, continuation of self factor, achevement and creativity factor, tradition factor, primary group ties factor. The korean youth think the most of achievement and creativity factor among five motivation factors. 2) The korean students have somewhat stereo-typed concepts of parental role and place the stress on training the behaviors of the child and encouraging the development of the child. 3) The sociodemographic variables to have relationship with the motivations for parenthood are age, sex, growth region and father and mother's educational degrees. And the variables related with the concepts of parental role are sex, father's occupational level. 4) There are relationships between traditional role concepts of a father and motivation of acquisition of social status factor and tradition factor. And traditional role concepts of a mother are related with motivations of acquisition of social status factor and primary group ties factor among the motivations for parenthood.

Given the rise in international tourism and the rapid growth of the Vietnamese economy, the hospitality industry in Ho Chi Minh City, Vietnam's commercial hub, has been facing severe labor shortages due to competition with other fast-growing parts of the economy. These struggles to acquire high-quality employees is strangling future growth and placing new importance on the role of recruitment. To better understand the effectiveness of an organization's recruitment strategy, recruiters need to ascertain the Job Pursuit Intention (JPI) of job seekers to efficiently align an applicant's work notions with the organization's goals. This study aims to investigate the factors impacting on JPI among employees working in the hotel sector in Ho Chi Minh City. Secondary data are from previous studies and primary data are from consultation with 10 experts, group discussions and five in-depths structured interviews with 15 random employees and 302 survey questionnaires with employees working in three five-star hotels. Cronbach's Alpha, EFA, T-Test, ANOVA are used for statistical analysis. The findings show that compensation, career advancement, and work-life balance affect JPI of job seekers, in which compensation is the most influential factor. Furthermore, recommendations for recruiters, further research and limitations of this study have been laid out.
